I am 36+3 weeks, I've been having the menstrual cramping like braxton hicks contractions for a while now. But last night I started having a new pain that feels like my uterus is bruised/tender. It happens on my lower belly, and sometimes up both sides. It does come with tightening, but they don't feel anything like the contractions I had with my first. At the same time, if my baby kicks, I get the same feeling. Like it's bruised and she just kicked it.

Anyone else? Is it cause for concern?
